The present invention relates to an automatic answering and reservation recording method of V.C.R. In particular, it is possible not only to execute an automatic answer to a telephone call from outside, but also a predetermined password and an input password from outside. The present invention relates to V. C. R. telephone reservation recording and automatic answering method in which data for reservation recording can be input and set only when there is a match.

In general, the recent development of V.C.R. has a built-in scheduled recording function in most cases. Such a reservation recording function has been widely used because it is convenient to reserve a desired program in advance, record the program at the time when the program is broadcast, and then view it again when necessary.

However, such a reservation recording function has a disadvantage in that it cannot execute data for reservation recording in the absence of a user.

Accordingly, V.C.R has been developed to enable scheduled recording from the outside using a telephone.Then, V.R. has been developed to solve the problem of malfunction between the answering machine and the built-in or externally installed telephone. A C. R. phone reservation recording and answering machine was developed.

1 is a schematic block diagram of a conventional V.C.R.phone reservation recording and answering machine.

As shown in FIG. 1, a conventional V.C. R. telephone reservation recording apparatus includes a switching unit 100, a ring detection unit 200, a signal decoder 300, and a microcomputer 400. And a voice signal generator 600.

When a call is received from an external telephone (not shown), a ring signal transmitted from an exchange (not shown) indicating that the call is received is transmitted through the switching unit 100 to an internal telephone (not shown) and a ring. It is transmitted to the detector 200. Then, the ring detector 200 forms a waveform of the received ring signal and converts the waveform into a pulse signal of a predetermined level and outputs it to the microcomputer 400.

Accordingly, the microcomputer 400 counts the number of pulses of the pulse signal provided from the ring detector 200 and generates a control signal to the switching unit 100 when the predetermined number of pulses is reached, and the switching unit 100 controls the control signal. In accordance with the connection from the outside from the incoming call to each other to be on-line. That is, the switching unit 100 is connected so that the tone signal input from the external telephone is transmitted to the microcomputer 400 through the signal processing unit 300.

If the number of pulses of the pulse signal recognized by the microcomputer 400 ends before the predetermined number is reached, the V. C. R. phone reservation recording device does not operate any more because it is in a state of receiving a call by the internal telephone.

That is, when the number of pulses of the recognized pulse signal ends before the predetermined number is reached, the microcomputer 400 provides the control signal accordingly to the switching unit 100, and the switching unit 100 records the telephone reservation of the V.C.Al. It is switched to disconnect the device from the external telephone.

On the other hand, the microcomputer 400 generates a control signal to the voice signal generator 500 at the same time as the on-line call from the external telephone. Accordingly, the voice signal generator 500 broadcasts a pre-stored announcement for the pre-stored recording, for example, if the automatic response function is desired, press the first key first and leave a message after the 'beep' sound, or make a reservation recording. If you want, press the 2 key and send a voice message to your external phone such as 'Enter date, start time, end time, data for channel'.

Thereafter, when a key signal for reservation recording is input from an external telephone, the signal processing unit 300 converts the signal into a binary signal of a predetermined bit and transmits the signal to the microcomputer 400, and the microcomputer 400 embeds it. To an internal memory (not shown).

When the scheduled recording is set through this process, as in the normal scheduled recording, the microcomputer 400 checks the current time of the built-in timer (not shown) and the scheduled recording time set in the memory, and the current time is the scheduled recording time. If it matches, V.C.R turns on and recording of broadcasting signal of set channel is performed.

In addition, when a voice signal is input after a key signal for an automatic response is input from an external telephone, the microcomputer 400 stores the signal processed and provided by the signal processor 300 in an internal memory. That is, the signal processor 300 converts an audio signal, which is an analog signal, into a digital signal and outputs the digital signal to the microcomputer 400, and the microcomputer 400 stores the audio signal in the internal memory. As a result, it will be appreciated that the signal processor 300 is composed of a tone decoder and an analog / digital converter.

In addition, after the microcomputer 400 receives a message reproduction request signal stored from the user through a key input unit (not shown), the microcomputer 400 transmits the message again through a speaker (not shown).

However, such a conventional V.C.R.phone reservation recording and answering machine can easily perform a reservation recording over the phone and can be reserved by anyone other than the user. There was a problem that could be run.

It is therefore an object of the present invention to provide a V.C.R.phone reservation recording and automatic answering method that allows a user to perform a scheduled recording only by a user by setting a password in advance, and even execute an automatic answering function.

According to a preferred embodiment for achieving the above object, the present invention, V. C. telephone reservation recording and automatic answering method for executing the telephone reservation recording and automatic answering function through an external telephone, (a) Detecting and counting a ring signal indicating that a telephone call has been transmitted from the outside through a telephone line; and (b) if the ring signal counted in step (a) matches a predetermined set number of times, talking with an external telephone. (C) determining whether a key signal is input for a predetermined time, and when the key signal is input, whether the signal requires a reservation recording or an automatic response. Determining whether the signal is a request signal; and (d) if the key signal input in step (c) is a signal for requesting an automatic response, a guide message for requesting a message input. Transmitting the message, storing the voice message input for a predetermined time, and ending the call; and (e) requesting input of a password if the key signal input in step (c) is a signal for requesting reservation recording. Determining whether the input password matches the preset password; and (f) if the input password matches the preset password in step (e), the current V.C. If it is possible to make a reservation recording, it sends a reservation recording guide message and hangs up the phone when the recording of the reserved recording data is completed, and if the current V.C.R is not available, the reservation recording is impossible. Hanging up the phone after transmitting the message; and (g) the input password in step (e) does not match the preset password. If a password is requested for a predetermined number of times, if the password input for the predetermined number of times matches within the predetermined number of times, the process returns to step (f). Hanging up the phone after sending the message.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart for executing a telephone reservation recording and automatic answering method of V.C.R, in accordance with a preferred embodiment of the present invention.

First, in step S10, it is determined whether a ring signal is detected through a telephone line. If a ring signal is detected in step S10, the ring signal detected is counted in step S20. That is, the microcomputer 400 counts the ring signal input from the ring detector 200.

In operation S30, when the number of times of counting the ring signal and the number of times of the auto-determined setting is smaller than the set number of times, the flow proceeds to step S200. If the counted number is greater than or equal to the set number, the process proceeds to step S40. At this time, the preset ring signal number is set in consideration of the time at which the telephone set can reach the telephone from the farthest distance from the telephone set and take the call.

Thereafter, in step S40, a call received from the outside is made on-line so that a call can be made, and then a guide message for setting the reservation recording and answering machine mode is sent to the external telephone. When step S40 is completed, in step S50 it is determined whether a key signal is input from an external telephone for a predetermined time, at which time, a reservation recording from an external telephone for a predetermined time, for example, about 10 to 15 seconds If the key signal for the automatic response is not input, it is determined that there is no intention to execute the automatic response or the scheduled recording, and the flow proceeds to step S200.

Then, in step S60, it is determined whether the input key signal is a signal for reserved recording or a signal for automatic response. If the signal is for automatic response, the process proceeds to step S80, and if it is a signal for reserved recording, the step ( Proceed to S70).

Proceeding from step S60 to step S80, in step S80, the telephone reservation recording and answering machine for executing the present invention is set to the answering machine mode, and the message input is requested in step S100. Saves the message. In step S130, the data input and storage time are checked, and when the predetermined time is reached, the process proceeds to step S200 to terminate the call and complete the auto answering function. Meanwhile. In the present invention, the predetermined time for storing the auto-answer message is about 1 to 2 minutes in consideration of the general telephone call time.

On the other hand, if the process proceeds from step S60 to step S70, step S70 requires the input of a password, that is, a password for executing reservation recording. In step S90, it is determined whether the input password matches the preset password. At this time, if the input password matches the set password, the process proceeds to step S120; otherwise, the process proceeds to step S110. Meanwhile, in the present invention, a preset password for reservation recording, that is, a password may be changed according to a user's intention.

Then, first, proceeding to step S110 in step 90, in step S110 counts the number of times the input password does not match the preset password, and in step S140 is counted in step S110 The number of times is compared with the preset reference number. If the counted number is smaller than the preset reference number, the flow returns to step S70 to repeat the flow from step S70, otherwise proceed to step S170. Here, the preset reference number may be changed according to the user's intention, but in general, about 2 may be appropriate.

Meanwhile, in step S170, a guide message indicating that a telephone is erroneously transmitted is sent to the external telephone. When step S170 is completed, the process proceeds to step S200 as in steps S50 and S130. In step S200, the call is ended and the flow ends.

In addition, if the process proceeds from step S90 to step S120, in step S120, it is determined whether the V.C.R is currently in a reserved recording state, and if it is possible, the flow advances to step S150. Proceed to S160.

When the process proceeds from step S120 to step S160, in step S160, the guide message is transmitted that the reservation recording is impossible, the flow proceeds to step S200, and the flow ends.

On the other hand, when proceeding from step S120 to step S150, in step S150, the V.C.R.phone reservation and answering machine used to execute the present invention is set to the reservation recording mode and scheduled recording. Send a guide message for. Thereafter, the process proceeds to step S180 to store the reserved recording data to be input, and when it is determined in step S190 that the storage of the reservation recording data has been completed, the telephone hangs up in step S200, after which the flow ends.

Therefore, the present invention can selectively and smoothly execute the telephone reservation recording and automatic answering functions, and in particular, only when a specific user who is familiar with the preset password is available to the telephone reservation recording, There is an effect that can prevent unnecessary telephone reservation recording.

While the invention has been shown and described with reference to certain preferred embodiments, those skilled in the art will recognize that various modifications and changes can occur without departing from the spirit and scope of the invention as set forth in the following claims.
